2.
a. fossil record
b. This is evidence of evolution because the fossilized bones show that animals existed in the past that are different from those alive today, proving that life has changed over time.
3.
a. DNA analysis
b. This is evidence of evolution because the differences in the gene sequences show how closely related species are; humans and monkeys share a more recent common ancestor than humans and chickens, which is reflected in their fewer genetic differences.
4.
a. comparative anatomy (analogous structures)
b. This is evidence of evolution because although honey possums and butterflies have similar functions (licking nectar with a long tongue), their tongues are made of different materials, indicating they evolved this trait independently to adapt to similar environments, not from a common ancestor with that trait.
